This detector looks for usages of libraries where the version you are
using is not the current stable release. Using older versions is fine,
and there are cases where you deliberately want to stick with an older
version. However, you may simply not be aware that a more recent version
is available, and that is what this lint check helps find.

!!! Tip
   This lint check has an associated quickfix available in the IDE.

(##) Example

Here is an example of lint warnings produced by this check:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~text
build.gradle:24:Warning: A newer version of com.google.guava:guava than
11.0.2 is available: 21.0 [GradleDependency]
    freeCompile 'com.google.guava:guava:11.0.2'
                -------------------------------

com.android.support:appcompat-v7 than 13.0.0 is available: 25.3.1

com.google.android.support:wearable than 1.2.0 is available: 1.3.0
[GradleDependency]
    compile 'com.google.android.support:wearable:1.2.0'
            -------------------------------------------

    androidTestCompile 'com.android.support.test:runner:0.3'
                       -------------------------------------
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here is the source file referenced above:

`build.gradle`:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~groovy linenumbers
apply plugin: 'android'

android {
    compileSdkVersion 35
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 17
        versionCode 1
        versionName "1.0"
    }

    productFlavors {
        free {
        }
        pro {
        }
    }
}

dependencies {

for the unit tests for this check to see additional scenarios.

The above example was automatically extracted from the first unit test
found for this lint check, `GradleDetector.testBasic`.

(##) Suppressing

You can suppress false positives using one of the following mechanisms:

* Using a suppression comment like this on the line above:

  ```kt
  //noinspection GradleDependency
  problematicStatement()
  ```

* Using a special `lint.xml` file in the source tree which turns off
  the check in that folder and any sub folder. A simple file might look
  like this:
  ```xml
  &lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;lint&gt;
      &lt;issue id="GradleDependency" severity="ignore" /&gt;
  &lt;/lint&gt;
  ```
  Instead of `ignore` you can also change the severity here, for
  example from `error` to `warning`. You can find additional
  documentation on how to filter issues by path, regular expression and
  so on
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html).

* In Gradle projects, using the DSL syntax to configure lint. For
  example, you can use something like
  ```gradle
  lintOptions {
      disable 'GradleDependency'
  }
  ```
  In Android projects this should be nested inside an `android { }`
  block.

* For manual invocations of `lint`, using the `--ignore` flag:
  ```
  $ lint --ignore GradleDependency ...`
  ```

* Last, but not least, using baselines, as discussed
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
